If you installed a radiator insulation, do not forget about it when you stalled, there is a sudden thaw in the yard (they've been pretty common lately) or even spring has come - otherwise you can overheat the engine even with a working electric fan of the cooling system.
Be sure to bring a shovel with you. To deal with deep snow (if he can meet on your way) best suited special "snowplow" or a shovel. For harder, packed or melted snow and digging out a car that has stalled in a rut, an ordinary bayonet shovel with a handle shortened for compactness is suitable. When traveling along forest roads, it is also desirable to have a hatchet to chop branches and put under the wheels, and sometimes for a fire.
If you regularly have to overcome slippery slopes, it is useful to carry a package in the trunk (small bag) with coarse sand, brick chips or something similar. It is often enough to throw a couple of shovels of this mixture under each wheel in order to move from a place and overcome a steep icy slope or not slide off the path, damaging the body.
